[0039] See figure 1 , The present invention is a multi-scene-based vehicle flow calculation method based on video images, and the steps are:
[0040] 1. Automatically generate traffic statistics line:
[0041] The traffic statistics line is a virtual line in the image, which is basically perpendicular to the road surface, the width is the same as the road surface area, and the height is about 1 / 2 of the road surface height. The selection of the traffic statistics line is mainly based on the actual situation that all cars will pass through this line, and the height is about 1 / 2 of the height of the entire road surface, which can effectively take into account the traffic flow information of up and down. Using the traffic statistics line scheme, we can wait for the target to pass at a fixed position, process the target in a targeted manner, and complete the calculation of vehicle flow according to the state change when the target passes the traffic statistics line.
